§112.4. Science, Grade 2.
The provisions of this subchapter shall be implemented by school districts beginning
September 1, 1998, and at that time shall supersede §75.28(a)-(f) of this title (relating to
Science).
(a) Introduction.
(1) In Grade 2, the study of science includes planning and conducting simple classroom and
field investigations to help students develop the skills of making measurements using
standard and non-standard units, using common tools such as rulers and clocks to collect
information, classifying and sequencing objects and events, and identifying patterns.
Students also use computers and information technology tools to support their
investigations.
(2) As students learn science skills, they identify components and processes of the natural
world including the water cycle and the use of resources. They observe melting and
evaporation, weathering, and the pushing and pulling of objects as examples of change. In
addition, students distinguish between characteristics of living organisms and nonliving
objects, compare lifelong needs of plants and animals, understand how living organisms
depend on their environments, and identify functions of parts of plants and animals.
(3) Science is a way of learning about the natural world. Students should know how science
has built a vast body of changing and increasing knowledge described by physical,
mathematical, and conceptual models, and also should know that science may not answer all
questions.
(4) A system is a collection of cycles, structures, and processes that interact. Students should
understand a whole in terms of its components and how these components relate to each
other and to the whole. All systems have basic properties that can be described in terms of
space, time, energy, and matter. Change and constancy occur in systems and can be observed
and measured as patterns. These patterns help to predict what will happen next and can
change over time.
(5) Investigations are used to learn about the natural world. Students should understand that
certain types of questions can be answered by investigations, and that methods, models, and
conclusions built from these investigations change as new observations are made. Models of
objects and events are tools for understanding the natural world and can show how systems
work. They have limitations and based on new discoveries are constantly being modified to
more closely reflect the natural world.
(b) Knowledge and skills.
(1) Scientific processes. The student conducts classroom and field investigations following
home and school safety procedures. The student is expected to:
B
(A) demonstrate safe practices during classroom and field investigations; and
B
(B) learn how to use and conserve resources and dispose of materials.

(3) Scientific processes. The student knows that information and critical thinking are used
in making decisions. The student is expected to:
(A) make decisions using information;
(B) discuss and justify the merits of decisions; and
(C) explain a problem in his/her own words and identify a task and solution related to the
problem.
(4) Scientific processes. The student uses age-appropriate tools and models to verify that
organisms and objects and parts of organisms and objects can be observed, described, and
measured. The student is expected to:
(A) collect information using tools including rulers, meter sticks, measuring cups, clocks,
hand lenses, computers, thermometers, and balances; and
(B) measure and compare organisms and objects and parts of organisms and objects, using
standard and non-standard units.
(5) Science concepts. The student knows that organisms, objects, and events have properties
and patterns. The student is expected to:
(A) classify and sequence organisms, objects, and events based on properties and patterns;
